Hi Mikael,

thank you, there are some interesting ideas.

We have already seen a lot of randomization in paths; duplicating a randomized 
path with varying saturation enhances the effect.

With PGF/TikZ I could maybe use a brush decoration on a path.

Is it possible to use a irregular "pen" in MetaPost? With transparency?
The MF manual says in 1.11, pens are limited, but not how.

Or are properties (MF manual 8.10) the way to go?
